Thousands of people flooded Tāhunanui Reserve on Sunday for the annual Weet-Bix Kids TRYathlon.
Organisers say 1500 children registered for the event, which saw them swim, bike and run their way around the beach and reserve.
The day kicked off with a collective warm-up shortly after 7.30am.
Age-groups then headed to the beach for the swimming leg of their race, running, diving and jumping through the fresh morning sea.
After completing the bike stage, it was a fast-paced run to cross the finish line where every kid received a medal.
Free breakfast was on offer for all, and activities kept families entertained for the morning.
The TRYathlon was cancelled last year, and it was clear that everyone was pumped to see the popular event back in Nelson.
